I wouldn't dig the potatoes until at least a day or two after every last tomato plant has been pulled up and bagged and put in the trash. This is because when you dig the potatoes, you need to let them air dry for a while to dry the skins before you put the potatoes into storage. There are differing recommendations as to how long you have to leave them out in the open air, but during this time your infected tomato plants will be releasing millions of Late Blight spores into the air. Those spores are going to float around your garden on air currents and a lot of them will land on the potatoes you just dug. Then when you put the potatoes into storage with their cargo of Late Blight spores, the spores will grow and you'll have a mess of rotting potatoes. I would wait until all the tomato plants are long gone.

.. I planted several batches throughout the month of September.... ......................... Hard to say if the harvest will be significant .. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ As I mentioned in my first comments, potatoes need AVERAGE 100 days(from sprout to harvest) I would say anywhere from 85 days to 110 days , depending on the variety, So say if you planted in mid September, It would be 60 days at mid November: NOT ENOUGH. I think SD area weather is good for two crops : spring and fall. For the fall you could plant them early August. For Spring , plant them in February.

Gary, So far, we like every variety and have no complaints. They've all been good so far. I haven't seen a single, storage issue of any sort and that's wonderful because lately I've been too busy to cook much of anything except brownies and cookies for the firefighters. I think I've baked 9 batches in the last two weeks. Some varieties are starting to leaf out a little bit the last week or so. I'm going to make a sweet potato pie or cobbler this weekend or on Monday for Tuesday's fire meals. (I guess if there are no big fires on Tuesday, which is unlikely, Tim and I will have to force ourselves, lol, to eat the whole pie or cobbler ourselves.) Fire activity is on the rise here, especially in our part of the county and we've had units out at fires pretty much every day. About the only time I'm "guaranteed" there won't be a fire is really early in the day when humidity is highest and wind is low. I'm having a hard time getting anything done, inside or outside, and feel like my seed-starting, planting and transplanting is falling behind more and more every day. Every time I step foot in the garden, the fire pagers go off so I'm almost afraid to step foot in the garden, but I'm about to go out there and work anyway (or at least attempt to work) since this will be the last day we have in the 70s for a few days. We're expecting frost here on Sun. a.m., and likely a light freeze (hopefully not a heavy one) as well, but I haven't put anything in the ground yet that cannot handle frost or a light freeze. Dawn

I've not tried potatoes yet, but it's interesting that both of you had such luck with store bought potatoes. Now I need to try. I'm still harvesting kale and Romaine, but they started to bolt in the last week. Spinach bolted a couple weeks ago. Zucchini and yellow squash are really starting to produce; I've had four or five of each so far. We had our first cucumber this weekend. Lots of tiny green tomatoes, but it'll be a while for them. Onions are getting really close. Enjoy those new potatoes. Michelle
